Honored ContributorYou probably need to use the data cache for normal program accesses to memory - otherwise it will be slower than slow.
Initially just use uncached accesses to the frame buffer area (if you aren't using the mmu, the easiest way to acomplish this is to set the high bit on the addresses). However you'll probably need to use the data cache flush and invalidate functions/instructions to give reasonable performance when accessing the buffers.
